Every time you log onto Facebook, Instagram, or Twitter to share a photo or post an article, you give up a piece of yourself in exchange for entertainment. Steemit, a nascent social media platform, is trying to change all that by rewarding its users with cold, hard cash in the form of a cryptocurrency. Everything that you do on Steemit—every post, every comment, and every like—translates to a fraction of a digital currency called Steem. Over time, as Steem accumulates, it can be cashed out for normal currency.
